Proving a problem is NP - complete by reduction from Vertex-cover. - Please see the attachment below for the complete question.
We need to prove that the problem is NP -complete by reduction from Vertex-cover.
Problem :- Given a collection of sets { S1, S2 ,..., S ...
Fully connected graphs - Is it TRUE or FALSE that ( and why )
In an undirected graph(with no self loops), if every vertex has degree at least n/2, then the graph is fully connected ?
Thanks
